Windows 10 Upgrade - Failed to Validate Product Key
Good morning all,
I am trying to upgrade one of our Laptops in our lab to Windows 10 Pro. It currently has Windows 7 Pro on it, and when I attempt to use the DVD copy I burned I am getting the dreaded "Setup has failed to validate the product key".
I went back to my settings and re-entered my product key again just to ensure that was not the problem and Windows 7 accepted it (again!) and activated my copy. However, when I ran the setup again it gave me the same error message and I am not able to continue with the install. And yes, I have tried using administrative credentials to no avail.
It's not defective media as I have already used this disk to upgrade another system to Windows 10 (however, the other system was a HOME install, not a PRO install). Further to that I tried using this disk on another Win 7 Pro install and it worked without incident. So I know it has something to do with the system or Win 7 Pro install itself on this PC.
When I try installing from boot it will not allow me to upgrade the current system - it tells me to boot into windows to complete an upgrade.
Any ideas? I checked the system logs and there is no mention as to why the install is failing. I'd prefer to do an upgrade as opposed to a full install as I have a lot of configs and settings that would be a major PITA to redo.
Thanks.
